Doudna and Charpentier Publish CRISPR-Cas9 Gene Editing Method
June 28, 2012 · 21st Century
Biochemists Jennifer Doudna and Emmanuelle Charpentier published a paper in Science demonstrating that the CRISPR-Cas9 system, derived from bacterial immune defenses, could be programmed with guide RNA to cut specific DNA sequences. Their team showed that a single synthetic guide RNA could direct the Cas9 enzyme to any target site in a genome, enabling precise, low-cost gene editing. The technique rapidly spread across laboratories worldwide, accelerating research in agriculture, disease treatment, and developmental biology. Doudna and Charpentier received the 2020 Nobel Prize in Chemistry.
